4pm - calm and sunny, perfect weather for opening up the hive again.
Our main aim today was to find the queen and mark her so that she'd be easier to spot another time, should we need to find her.
It's a good idea to do this as soon as possible because with every week that passes there will be hundreds more bees each time as more and more bees hatch out.
We went through every single frame, trying to spot how recently the queen was on it, by examining the size of the larvae to see how recently the eggs have been laid. We found a frame with eggs less than one day old (they are the same shape as but about a quarter of the size of a small grain of rice and stand up straight on their tip end at the bottom of the cell) but we couldn't spot her.

As the bees were very calm still we went through every frame once more trying to find her but then had to give up. It's a bit frustrating, especially knowing that it'll be even harder to spot her next time we look, but at least finding day-old eggs proves that she is definitely there and didn't get lost during the transfer!
